So... I was wondering what the impact of splitting up the card compilation by e.g. generation would be. Depending on the split things would get fairly intertwined, so I thought I'd start small. This just splits NVC0 from everything else. I figure that for the people this matters the most to, NVC0 is the least relevant card -- people with sub-1GB of RAM, older hardware.
With my config options and everything compiled, the total size of nouveau.ko is 1343324 bytes (incl symbols), which is split up
text data bss dec hex filename 579171 184264 480 763915 ba80b ./drivers/gpu/drm/nouveau/nouveau.ko
Turning off nvc0+ gives us 995667 bytes, split up
text data bss dec hex filename 472244 59528 480 532252 81f1c ./drivers/gpu/drm/nouveau/nouveau.ko
So we lost 100K of text and 130K of data (probably all that pgraph fw), and the remaining 100K must be symbols. (I'm not stripping because nobody in their right mind strips these kernel modules.)
In a local patch that also lops off pre-nv50 cards (with one small problem that involves moving a function somewhere -- seems like nouveau_crtc_set_config is defined in dispnv04 but used outside of it -- which I haven't done yet) the module size goes down to 721366, split up as:
text data bss dec hex filename 346212 34727 480 381419 5d1eb ./drivers/gpu/drm/nouveau/nouveau.ko
So another 130K of text, 26K of data, and 130K in symbols (?). I didn't have to do anything too dirty, with the mild exception of the device/base.c file which had that giant if statement, which will have to be done a bit more cleverly now to not end up as a maze. My final exercise will be to try to lop off nv50 as well, making the driver ~useless, but still interesting as it would allow one to only compile one of the 3 categories (or any combo).
Here's some further size info:

The final patch that does all this is not much dirtier than this patch, just more changes to the Makefile. I'll hold off on sending it out though, awaiting some feedback on whether people think this is useful and/or should be done differently.
The impact to the code is pretty minor. Depending on the situation it's easier to either ifdef out code or to provide stubs for functions.
What do people think about this? It shouldn't be too difficult for me to extend this to categories like <pre-nv50> <nv50-nvc0> <nvc0-nve0> <nve0+>, or maybe even more fine-grained, esp since nvd0 is when a lot of changes happened. Or maybe less-fine-grained and keep the nvc0/nve0 cards under one option.
Feedback appreciated.
